Shrubs, erect, rarely trailing, usually tufted, 2–4 (–8) dm. Twigs pale reddish to purplish, becoming gray to dark gray, puberulent and sparsely stipitate-glandular, becoming glabrate. Leaves aromatic; petiole 0.5–2 mm, sparsely puberulent and sessile-glandular; blade dark green abaxially, light green adaxially, elliptic to elliptic-oblong, 10–25 × 5–12 mm, base cuneate, margins entire, usually plane, apex obtuse, usually apiculate, surfaces glabrous or sparsely sessile dotted-glandular abaxially, densely covered with sessile crystalline-punctate glands adaxially. Inflorescences erect, (5–) 7–12 (–15) -flowered; bracts leaflike. Pedicels 1–2 cm, hairy, glandular. Flowers: calyx lobes light purple, ovate, 3–5 mm, margins ± glandular-ciliate; corolla rose to deep pink, (12–) 14–20 mm diam., petal ridges connected between corolla lobes, lobes connate ca. 1/2 their lengths, abaxial surface ± puberulent and glandular apically (throat puberulent or glabrous); filaments 3–7 (–10) mm, rarely ciliate basally; anthers purple, oblong, 0.7–1.8 mm; style dimorphic, 7–10 mm (long form), 3–6 mm (short form); ovary puberulent, dotted-glandular. Seeds 0.3–0.7 mm. 2n = 24.
Phenology: Flowering late spring–early summer.
Habitat: Open sunny ridges in xeric shrub community or sparse woodland, rooted in shallow or, more often, deeper soils, on a range of substrates, often including ultramafics
Elevation: (200-)600-1400 (-2100) m
